The EQEP peripheral contains a 16-bit watchdog timer that monitors the quadrature-clock to indicate proper operation of the motion-control system. The EQEP watchdog timer is clocked from SYSCLKOUT/64 and the quadrate clock event (pulse) resets the watchdog timer. If no quadrature-clock event is detected until a period match (QWDPRD = QWDTMR), then the watchdog timer will time out and the watchdog interrupt flag will be set (EQEP_QINT_EN_FLG[20] WTOI_FLG). The time-out value is programmable through the watchdog period bit field (EQEP_QWD_TMR_PRD[31-16] QWDPRD).
